You said how I feel! I too have left this site for numerous reasons. #1 being I feel as though I dont fit in. I am afraid to post at times because of rejection as well.
I know exactly how you feel. As a matter of fact I had left again, and deceided to read some posts. When I read your response, I said to myself. "that's exactly how I feel" I know it's my problem and no one else but I cant help the way I feel.
It seems as though life is full of cliques. And, there are cliques here as well. I do love to come here and visit. But I chose to just keep to myself.
